I was wondering if it is possible to use feed keys for only some keys. Essentially what I have is posts that anyone can see, and posts that are only for subscribers/members. I accomplished this in what seemed the simplest way, by using Role Manager to allow private posts to be visible to subscribers.
Now the only thing is figuring out RSS feeds. One feed for subscribers that could includes everything, but use a feed key... and another feed for non-subscribers that only includes the public posts.
Thanks for your help,
